Q: How do I set or change the kernel settings?
A: Use an app like Trickster to control the kernel settings.

Q: Why do some developers use an install script to set the kernel features and others use a control app?
A: To each his own. I personally like the flexibility of a control app so I can change settings on the fly and monitor the cpu frequencies/temperature etc. in lieu of changing the script and rebooting each time.

Q: Will you add this feature?
A: Maybe if you provide me with a good reason and research backing up why it's good to add. I like to keep my kernels somewhat clean to maintain optimization on battery and performance without going overboard.
